In this study, hydrogels based on chitosan cross-linked by glyoxal have been investigated for potential medical applications. Hydrogels were loaded with tannic acid at different concentrations. The thermal stability and the polyphenol-releasing rate were determined. For a preliminary assessment of the clinical usefulness of the hydrogels, they were examined for blood compatibility and in the culture of human dental pulp cells (hDPC). The results showed that after immersion in a polyphenol solution, chitosan/glyoxal hydrogels remain nonhemolytic for erythrocytes, and we also did not observe the cytotoxic effect of hydrogels immersed in tannic acid (TA) solutions with different concentration. Tannic acid was successfully released from hydrogels, and its addition improved material thermal stability. Thus, the current findings open the possibility to consider such hydrogels in clinics.

Surface immobilization of Jagged1 promotes odonto/osteogenic differentiation in human dental pulp cells. On the contrary, soluble Jagged1 fails to activate target gene expression of Notch signaling which is important for differentiation of human dental pulp cells. Hence, Jagged1 delivery system is indeed required for transportation of immobilized Jagged1 to promote odontogenic differentiation of human dental pulp cells in vivo. The present study described the preparation and characterization of Jagged1-bound fibrinogen-based microspheres. Water-in-oil emulsion technique was employed to prepare fibrinogen microspheres and thrombin cross-linked fibrinogen microspheres. The average size of fibrinogen microspheres and thrombin cross-linked fibrinogen microspheres was 213.9 ± 35.9 and 199.9 ± 41.9 µm, respectively. These microspheres did not alter the human dental pulp cells’ cell viability. Human dental pulp cells were able to attach and spread on these microspheres. Jagged1 was conjugated on microspheres using 1-ethyl-3-(3-dimethylamino) propyl carbodiimide/N-hydroxysuccinimide. Binding capacity of Jagged1 on both fibrinogen microspheres and thrombin cross-linked fibrinogen microspheres ranged from 25.8 ± 6.0 to 35.6 ± 9.1%. There was no significant difference in the size of microspheres between before and after Jagged1 conjugation process. In conclusion, fibrinogen microspheres and thrombin cross-linked fibrinogen microspheres could be utilized as the alternative biomaterials for Jagged1 delivery for future biomedical application.
